Abstract:
Three series of 2-thiazolylhydrazines were synthetized and evaluated for their MAO inhibitory (MAOI) activity, both by in vivo tests, to assay their influence on several MAOI activity-related parameters (the variation on blood pressure induced by tyramine and clonidine and L-amfetamine-induced hypermotility) and in vitro tests, to assay their effect on rat brain mitochondria by a kinuramine fluorimetric assay. In vivo, all the tested compounds significatively influenced the evaluative parameters used. As regards in vitro test, all compounds displayed MAOI activity at a concentration of 1.10(-4) mol.l-1, which was significant in several cases. In the discussion of the results, the influence of the structure on the biological activity of the prepared compounds was delineated.
